A flashing green key light on your 2014 Honda CR-V indicates the immobilizer system is not recognizing the key, preventing the engine from starting. To troubleshoot, try replacing the battery in your key fob, using a spare key, or ensuring a blown immobilizer-related fuse is replaced. If these steps fail, the problem likely requires professional diagnosis and potential reprogramming by a Honda dealership or a specialized repair shop with diagnostic tools.

Immediate troubleshooting steps:

1. 1. Check the Key Fob Battery:

   A weak or dead key fob battery can prevent the immobilizer from recognizing the key. Replace the battery with a fresh one.

2. 2. Use a Spare Key:

   Try starting the vehicle with your spare key. If the spare key works, the issue is likely with the original key's transponder chip or fob.

3. 3. Inspect for Fuses:

   Check the fuses related to the immobilizer system. A blown fuse can cause this issue, especially after work on the vehicle.

4. 4. Lock and Unlock Doors:

   Some users have reported that locking and unlocking the doors with the key can sometimes reset the system and resolve the issue, particularly after a low battery.
